JOHN LINDER, 0F MEADOWLANDS, MINNESOTA, ASSIGNOR OF ONE-HALF T0 CHARLESMAURER, OF BOVEY, MINNESOTA.

CORN-HUSKER.

Application filed July 31, 1911.

To all whom it may concern:

Be it known that I, JOHN LINDER, a subject of the King of Sweden,residing at Meadowlands, in the county of St. Louls, State of Minnesota,have invented certain new and useful Improvements in Corn- Huskers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to corn husking machines, and has for an objectto provide a device of this character that will have novel means fortwisting the ear from the fibrous stem containing the husk.

A further object of the invention is to provide a novel means forholding the fibrous stem stationary during the twisting of the eartherefrom.

A still further object is to provide a device of this kind having anovel cam ring that will actuate the ear clutching fingers of the deviceso as to positively prevent their accidental displacement.

A still further object is to provide a device including a sliding earsupporting head, and stationary resilient fingers equipped with curvedtips forming a stripping ring which pushes back the husk from the tip ofthe ear upon the head being manually slid toward the ring.

With the above objects in view the inven tion consists in certain noveldetails of con struction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claims.

showing the tips of the husk spreading fingers and the tips of the eargripping fingers,

The device is designed to be supported on a portable truck designated ingeneral by the numeral 10. Rising from the floor of the truck adjacentto one edge are spaced standards 11 which are connected at their upperends by a rod 12, this rod forming a pivotal support for an earreceiving trough 13, lugs 14 being formed on the rear end of the troughto receive the rod. For yieldingly supporting the inner end of thetrough, a pair of standards 15 are arranged on opposite sides of thetrough and are terminally equipped with helical springs 16, lugs 17 and18 projecting from the edge of the trough and standard respectively andengaging in the bores of the springs to secure the springs in position.

The longitudinal edges of the trough are bent outwardly and form guides19, and arranged to slide on the trough is a plate 20, having transversestrips 20 formed with downwardly bent extremities 21 which embrace theguides of the trough. A circular head 22 is fixed to the inner edge ofthe plate and conforms to the contour of the trough, this plate beingequipped on its operating face with a radial series of toothed angleirons 23 and further being formed with a segmental notch 24:- whichextends about to the center of the head. The fibrous stem on the ear ofcorn is impinged against the toothed angle irons so that the latterpenetrate into the stem and prevent rotation of the ear of corn in thetrough. The purpose of the notch 24: is to permit of the operators handbeing thrust forwardly through the head in mounting the ear of corn asdescribed. The head is manually moved forwardly along the trough toadvance the ear of corn to the husking mechanism, a handle 25 beingfitted to the plate 20 to facilitate this movement.

Mounted to turn in spaced pedestals 26 is a stub shaft 27, one end ofwhich is equipped with a driving gear 28 and the opposite end of whichis equipped with a circular head 29; Extending forwardly from the headare husk spreading resilient fingers 30, the tip ends of the fingersbeing bent toward each other as shown at 31, and then terminally andoppositely bowed as shown at 32, these bowed portions cooperating informing a ring which engages the tip of the ear of corn between thekernels and the husk, and as the ear of corn is moved longitudinally ofthe trough, strip or spread the husk from the ear as shown in Fig. 4,the fingers rotating constantly during this movement of the parts andyielding slightly to conform to the contour of the ear. In so much asthe bowed terminals of the fingers do not form a continuous ring, byrotating the fingers the in ner surface of the husk is acted upon as ifa continuous ring was presented while at the same time, the sharpenedtips of the fingers maintain their function of tearing loose from theear any portion of the husk which may have a tendency to stick to theear.

Extending forwardly from the head 29 and approximately in parallelismwith the husk spreading fingers are fingers 33, the tip ends of thesefingers being equipped with transversely disposed arcuate saws 34 whichare disposed in rear of the ear stripping ring, and are designed topenetrate the ear at a predeterminedstage in the husking operation. Thebase ends of the fingers 33 are bent outwardly from the head 29 as shownat 35, and thence bent inwardly to intersect the husk stripping fingers30 as shown at 36. The inclined portions 35 of the fingers are equippedwith idlers 37 which bear upon the inner periphery of a substantiallyfrusto-conical cam ring 38, this cam ring being moved forwardlysimultaneously with the advance of and toward the advancing ear of cornand serving to move the fingers 33 toward each other so that the saws atthe tips of the fingers penetrate into the ear of corn and positivelygrip the ear. The shaft 27 is rotated constantly causing the rotation ofthe ear and serving to twist the ear from the fibrous stem and clinginghusk. The cam ring is now moved rearwardly and the gripping fingersspring out from the car so that both the ear and husk may beindependently removed from the device.

To mount the cam ring for sliding movement, a pair of parallel guiderods 39 are arranged in horizontal position on opposite sides of thering, the ends of these shafts be ing supported by suitable standards40. Orificed lugs 41 project from opposite sides of the cam ring andengage these rods. Pivotally secured at their upper ends to one of thelugs and to one of the guide hooks of the plate 20, are links 42 and 43,respectively, the inner ends of these links being connected by a rocklink 44 which is pivoted approximately centrally to one of the standards40. By virtue of this train of links, as the ear holding. head is beingadvanced longitudinally in the trough, the cam ring will besimultaneously advanced along the guide rods in the direction of thetrough and serve to move the saws of the gripping fingers intoengagement with an ear as above described, it being understood that thehusk is stripped from the ear by the stripping ring prior to theengagement of these saws with the ear.

For rotating the driving shaft 27 in order to twist the ear from itsfibrous stem as above described, a gear 45 is mounted to turn on a stubshaft 46 carried by a pedestal 47 secured to the floor, this gearmeshing with the driving gear 28. A treadle 48 is centrally pivoted to asuitable hanger 49 secured to the floor, and is equipped with anupstanding link 50, the upper end of which is swivelly mounted on awrist pin 51 projecting the gear 45. Upon depression of the treadle, thegear 45 will be rotated constantly, and through the instrumentality ofthe gear 28 will cause the rotation of the shaft 27.

In order to adjust the relative positions of the stripping and grippingfingers, the base ends of both sets of fingers are formed integral withplates 53, each plate being provided with a longitudinal slot 54 throughwhich retaining screws 55 carried by the head 29 projects, an adjustingscrew 57 carried by the plate also projecting through this slot andpermitting of the plate being adjusted radially on the head. Thisadjustment permits of the stripping and gripping fingers being movedtoward or away from each other as desired.
